Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed December 15, 1905. Serial No. 291,867.

To all whom fit1/icy concern:-

Be it known that I, EDGAR I. BEOOMALL, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful 'Improvements in Cream Separator-s, of which the following. is'a specification. l

This invention relates to cream separators. Its object-.is to. produce a separator of simple and strong construction, that can be easily taken apart for the purpose of cleaning or repairing. .f

In the drawings Figurel. is a side view of a separator partially in section; Fig. 2 isA la vertical section, enlarged, of part of the separator shown in Fig. l; Fig. 3 is a vertical section on the line 3 3 of Fig. 1; Fig. 4 1s a cross section on the line LA of Fig. 2

showing details; Fig. 5 is a cross section onl the line 5 5 of Fig. 6; and Fig. 6 isa side view of the part shown in Fig. 5.

A representsa standard of'suitable form to support the separator. A casing on the top of the standard contains the operat- 'v ing mechanism, and above this is'a tank C Charged to contain the milk supply which is distherefrom into the separator through the cock D.

The rotary se arating bowl E is con tained within t Ve lower casing F. The

separating bowl E has at its upper lend ducts e throughfwhich the fresh milk is admitted to thebowl. The cream is discharged from the`bowl through the ducts c, and the milk through ducts not shown in the drawings. The bowl E is attached to the vertical spindle G in any suitable manner, so that it v'is rotative therewith .and removable therefrom. The spindle G entends through the casings B and F. At itsupper end it is journal'ed Ain a bearin comprising the cup g, the ring g and .the all bearings g2, while its lower end is'supportedv in the step bearing g3. vForl the purpose of rotating the spindle G a.' gear H 1s shown that meshes withthe worm G .on the upper end of the spindle. 4The gearII is turn operated by .suitable gearing A(indicated by dotted lines in Fig. l), conneetedwitha hand operated crank or other driving means. Access is had to the casing'F which contains the sepa-- ratin .'bowl, by means of the removable cap I. L Illiis'ca vIwhich contains the step bearing'jgB fort espindlenG, also contains other partsof the separator, presently to be4 de.v

scribed, when locked to the casing F. One of the locks that secures the cap I to the ,casing F is shown in Fig. 3, and is a pin i that is pivoted atz" between lugs 2, 2 on the cap I, and which is adapted to enter between corresponding lugs f, f on the casing F, and to be secured thereto by the thumb screw f. I

The cap I is provided With a flange I that receives a vertical guide rod J secured 'receives the cream from the separating bowl is a closed pan M, which fits upon and covers over the pan L. The pan M incloses the milk discharge ducts leading from the separating bowl, and has an outlet m that leads to the cream discharge spout K.

From the above description, it is obvious that when the ca Iis-dropped from the casing F, the step hearing g3, and thepans L and M are removed. It is also apparent that the separating bowl .is exposed when these parts' are removed, .so that 'it too can be readily removed from the spindle after the cleft disk N (see Fig. 5) has been withdrawn from the groove in the spindle indicated by dotted lines in Fig. 5. y

lhenthe cap I is removed from the casing F, t 1e spindle G'drops until the shoulder O (see Fig. 4) engages the tapered socket b in the casing B. This shoulder O has a straight-edge o, which when it engages 4the tapered socket 5 holds the spindle against rotation. In this position of the'spindle its upper end, above the connection with the driving mechanism, is still within the bean,

ing. cup g. The shoulder O and bearing cup g bracethe spindle to resist the strain incident to removing and replacing the bowl upon its lower end.

The operation of the 'separator is as fol lows: The separator bowl is set in motion, and the milk that is to be separatedy is drawn from the reservoir or tank C int a`unnel P, which leads to the trough Q.

, his latter is.

A attached toa collar Q that encircles the trame; a removable step bearingn for said theducts not shown to the spindle, rotatively supported therein; a re movable step bearing` for said spindle; drivingr said bowl upon said spindle; and a` sup- -port upon said trame for said. step bearing spindle and extends downto the, ducts e, through which the milk is admitted to the separating bowl. The collar Q is large enough for the milk to pass between it and the spindle. In the l separatingl bowl the fresh milk is separated under the centrifugal force generated by the rotation of the bowl into cream that passes out through the ducts e to the panlvl and thence to the spout K, and skimmed milk that passes out through pan L and thence to the spout K.

What I claim is 1. In a centrifugal separator, 'the combination with a suitable frame, ot a vertical ing mechanism for said spindle; a separat- Fingbowl; and means for detachably securing lsaid bowl upon said spindle, below its connection with said driving mechanism, whereby said bowl is adapted to be withdrawn from the lower end of said spindle.

2i In a centrifugal separator, the combination with a suitable frame, of a vertical spindle, rotatively supported therein; 'drivingmechanism tor said spindle; a separator bowl; means whereby said bowl is remov- 'ably supported-upon' said spindle, below its connection with the driving` mechanism; a removablecasing around said bowl; and a step bearing for said spindle, within said removable casing and removable therewith. 3.' In a `centrifugal separator, the combination with a suitable frame, of ay vertical spindle, rotatively supported therein; driving mechanism for said spindle; a separator bowl; means whereby saidv bowl is removably supported upon said spindle, below its connection with the driving,mechanism; a fixed casing inclosingr the upper part of said bowl; a removable casing inclosing the rcmainder oi said bowl; detachable means whereby the lower casingl is supported by the upper casing; and a step bearing for said spindle wit-hin said removable casing and removable therewith.

4. In a centrifugal separator, the combination with a suitable frame, of a vertical spindle, rotatively supported within said spindle; driving mechanism for said spindle: a separatorbowl; means for detachably secu radapted to sustain both said bearing and said shaft, and having a sliding connection with said frame, whereby, when released, it falls away from said spindle to permit the bowl to be withdrawn from said spindle.

In a centrifugal separator, the combination with a suitable frame, of a vertical spindle, rotatively supported therein; drivinamechanism for said spindle; a separator bowl; means whereby said bowl is removably supported upon said spindle, below its connection with the driving mechanism; a removable casing around said bowl; and r'emovable vessels contained within said casing', adapted to receive, respectively, cream and skimmed milk from said bowl and to deliver them to suitable discharge spouts; substantially as shown and described.

6. In a centrifugal sci iarator,ftlie combination with the vertical. rotary spindle G, having the shoulder with the straight edge o, ot' a suitable trame having' the tapered recess L adapted to engage said shoulder O when the spindle falls trom its operating position; driving mechanism for said spindle located above said shoulder; and a fixed part adjacent to said spindle, above said driving mechanism, and adapted to brace said spindle against. lateral pressure when its shoulder O is in engagement with said recess substantially as shown and described. l

'l'. In a centrifugal xseparaten the combination with a suitable frame, of a vertical spindle, rotatively supported therein; and having` a transverse lgroovey at its lower end; drivingmechanism for said spindle: a separater bowl adapted to t upon said spindle; and the slotted disk il adapted to entersaid groove in said spindle and to removably sup port said bowl; substantially as shown and described. .A

8. In a centrifugal separator, the combination with a suitable trame, of a. vertical spindle` rotatively supported. therein; driving mechanism for said spindle; a separator bowl attached to one end of said spindle;

the verticalguide rod lJ in said frame; the

casing I, adapted to contain the bowl, and slidingly attached to said rod by the iange I: and means for locking said casing in position around said bowl substantially as shown and' described. d.
